Define, Control, and Analyze GNSS Simulation Scenarios

Testing global navigation satellite system (GNSS) receivers requires precise control over satellite constellations, signal environments, and error conditions — all delivered as repeatable, lab-based scenarios. Keysight simulation control software provides modular tools that define, execute, and analyze positioning, navigation, and timing (PNT) test scenarios on PNT X, GSS7000, and PNT Xe signal simulators. Three core position application tools (SimTEST, SimREPLAYplus, and SimGEN) offer a tiered upgrade path from entry-level scenario replay to full parameter definition with real-time control. Specialized add-on modules extend the platform into 3D multipath simulation, hardware-in-the-loop integration, inertial sensor emulation, and encrypted signals testing.

Tiered Scenario Control

Choose from three position application tools — entry-level replay, mid-tier scenario creation, or full-capability simulation definition — and upgrade as test requirements grow.

Multi-Constellation Coverage

Simulate GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS signals across multiple frequency bands with support for up to 63 satellites per constellation.

Realistic Environment Modeling

Reproduce real-world signal conditions with 3D multipath and obscuration simulation, inertial sensor emulation, atmospheric error modeling, and hardware-in-the-loop integration.

Modular Extensibility

Add specialized capabilities — LEO orbit propagation, I/Q capture and replay, MEMS sensor fusion testing, or classified M-Code simulation — as mission requirements evolve.

Highlights

SimIQ enables Keysight’s GSS7000 and PNT X GNSS simulators to capture, replay, and share I/Q data files without additional hardware — allowing teams to test receiver algorithms earlier in the development cycle.

  • Validate GNSS software receivers by injecting generated I/Q data, removing RF real-time constraints and enabling parallel simulation at scale
  • Test receiver algorithm models before real hardware is available, then reuse the same I/Q scenarios to validate the hardware front end
  • Generate RF output including GNSS signals, custom waveforms, custom noise, and interference or jamming events to address emerging GNSS vulnerabilities
  • Replay confidential I/Q data files on the same hardware used for civilian signal testing, supporting classified signal and code workflows with fewer security concerns
  • Share I/Q files across global teams for consistent, repeatable playback at every stage of the development cycle
